Description

Purifying Foaming Wash Hyalu B5 Hyalu B5 Cream Anthelios Ultra How can I maximize the benefit of Hylau B5? For the deepest hydration, apply Hyaluronic Acid to damp sink to maximize absorption. We recommend that you mist your skin with our Thermal Spring water before use. Dont forget to lock in moisture with a moisturizer. Why is Hyaluronic Acid effective for anti aging? This skincare ingredient can hold up to 1000x its weight in water, which is important considering as we age our skin loses the ability to hold onto water and stay moisturized—causing visible loss of plumpness and suppleness in our skin’s appearance.

I’ve been using this serum consistently and I’m very impressed with the results. The formula absorbs quickly, feels lightweight, and leaves my skin soft, smooth, and hydrated throughout the day. It gives my skin a healthy, plump appearance without feeling greasy. Ialso have sensitive skin, and this serum did not cause any irritation or breakouts. It layers well with the rest of my skincare routine and helps keep my skin looking refreshed and moisturized. a great addition to any skincare routine, especially if you’re looking for extra hydration. ... show more

I bought this 3 la roche posay set coz I want to lighten my face as am always expose cleaning our swimming pool everyday and florida weather made my skin darker. I dont use skincare coz im lazy and busy and has sensitive skin but I found this brand from my flight attendant friend coz her skin was amazing!!!and ddnt think twice to try bcoz of her! - Mela b3 - to lighten my face (day and night use) - Hyalu b5 - to hydrate my face and help with fine lines in my eyes, anti aging serum (day and night use) - Hydraphase- for dehydrated skin and dull complexion (day and night use) When I wrote this feedback its my 6th day using it and am so happy so far. No breakout, not affecting my skin, no stings, no weird side effects in my face, it feels really good in my face and my make up became awesome looking its not caky anymore and no more annoying lines from my foundation , thats when i found out my skin is normal to dry skin (i get caky and lines when im on foundation) and these set helps me a lot!!! Hoping to bring back my lighter face soon with mela b3!!! About the seal and authenticity I searched about it too I was bothered of not having seal so I made a research and found this •No, not every La Roche-Posay product is sealed some come simply in a box with no wrapping or seal. • Yes, some items feature protective elements like QR codes or holograms for authenticity. • Packaging styles can differ depending on the product type and region. If you’re ever unsure, you can usually check authenticity by scanning the QR code (when present) or verifying the product through their official website or app. Negative part, Its little pricey but so worth it!!! ... show more

    • Expensive but effective
Size: 1.01 Fl Oz (Pack of 1)
One of the best HA serums on the market and nice splurge when you want something French and fancy sounding. It hydrates and plumps fine lines as advertised without being heavy nor greasy. It does have a fragrance, but it is pleasant and mild. I was concerned it would irritate my very sensitive skin and rosacea, but pleasantly surprised after a month of daily use, zero problems. I use it in combination with the Double Repair moisturizer. My dermatologist has been pretty impressed with the health of my skin lately. In complete fairness, there are other HA serums on the market that are as effective, use the same ingredients and concentrations, at half to a quarter of the price (The Ordinary, for example.) YMMV ... show more

    • Effective anti-aging
Size: 1.01 Fl Oz (Pack of 1)
My favorite skin care product I have ever used. It instantly brightens my skin and has a luxuriously soft consistency. It dries quickly so I can continue applying other products and for how small the bottle is, it lasts really long. It makes your skin feel moisturized without making it greasy.

Nice texture. Don’t love the smell. A bit perfumy. It is non greasy and goes into the skin well and feels nice . I have not had any results I can see yet but has only been about a week. I like to apply it morning and night before my moisturizer. It does feel like an added benefit for my skin. The bottle is blue but the serum is clear. ... show more

    • Hydrating serum that leaves skin soft and plump
Size: 1.01 Fl Oz (Pack of 1)
Review Image by sandra M Cardenas
I bought this serum because I needed extra hydration, especially with my busy schedule and long work shifts. The texture is lightweight but very hydrating. It absorbs quickly and leaves my skin feeling soft and smooth without being greasy. I use it before my moisturizer, and it layers well with other products. I’ve noticed my skin looks more hydrated and feels more comfortable, especially on days when it feels dry or tired. Pros: very hydrating, lightweight, smooth texture, good for daily use Cons: a bit pricey for the size Overall, this is a great serum if you’re looking to improve hydration and keep your skin looking healthy. ... show more

    • Best brand and product.
Size: 1.01 Fl Oz (Pack of 1)
I like that it delivers noticeable moisture and plumping effects without feeling heavy or greasy. The hyaluronic acid helps draw water into the skin, which can make skin look smoother and more refreshed pretty quickly. The addition of vitamin B5 also helps soothe and support healing, so it’s often recommended for dry, irritated, or slightly compromised skin. The texture is slightly gel-like but absorbs well, layering nicely under moisturizer and makeup. It’s also fragrance-free, which is a big plus for sensitive skin users. ... show more
